I am 29 year old and we are trying to conceive from last 6 months.

My periods were on 31st December 2012 and 29 days cycle.
I am expecting my periods on 28th January 2013 and today am 2 days late,
But on 27th January i saw pink color spot when i wiped but after that i saw nothing.
After 3 days 30th Jan again pink color spot and am very disturbed as am expecting my pregnancy this month.

Please help me , Is it implantation bleeding?

Or my periods are coming.

Thanks in advance .
